Itron User Interface Automation | Quality Assurance

I designed and automated user interface tests for Itron Enterprise Edition (IEE), an electricity meter data management platform. For the first time, this allowed automation testing on the user interface rather than manual test execution. I trained with the USA team and provided training to the India team to help build a large suite of automated tests.

SolveXia Build, Test, and Deploy Automation | DevOps

I designed and built the continuous integration platform to build, test, and deploy SolveXia's automation platform to testing, staging, and production environments. This was originally a manual process and was subject to many human errors and consumed much of the staff's time to perform. I initially used Octopus Deploy and later Azure DevOps to perform this task, allowing SolveXia to build, test, and deploy at a click of a button by any employee, not just the development team.

Brite Decking Stock Tracking Dashboard | Data Reporting

I built a stock reporting dashboard for Brite Decking, a company that sells polymer decking products. Previously, Brite Decking kept track of stock using spreadsheets, but this was not practical and was subject to many errors. Using the API in Quickbooks Online, Google Cloud Platform, and Power BI, I built a live dashboard that can be accessed by key stakeholders to ensure they know how much stock can be sold to clients. This allowed for greater visibility of all stock quantities and less time spent dealing with complex spreadsheets.
